so now I have my solar panel, charge controller, and inverter, and now need to choose batteries...I have looked at my local tsc, ct, Walmart, jobber stores, and battery expert and it seems that Walmart is the place that is gonna get my money as they have a grp 29 for $84 and a grp for $79, best price per ah I could find...but the one red flag was the 27 had a ah rating of 120 while the 29 had 114....I was pretty confused and held off on pulling out the wallet because that didn't make sense....why would the physically smaller battery, less expensive battery have more ah?? or is this just smoke and mirrors with the labels...I thought the heavier the battery, the better?? or am I mistaken?
